solar keymark 100L split pressurized solar water heater
Product Detailed

split pressure solar water heater:
1.CE,Solar Keymark,SRCC
1.pressurized water tank,
2.heat pipe collector
3.work station

Advantages

solar collector separates with water tank, combining with the building perfectly

The tank loses less energy than the normal one

the electric heater is used so that in the day without sunshine hot water can also be used

The heat-pipe is conducted by heat transfer medium liquid,no water in the vacuum tube.So the system can normally work even some tubes are broken.

It's used for warming, hot water for home cooking use, bathing etc 


Working principle

The collector absorbs solar energy and transmits it to the water tank through circulation.When the temperature of the collector reaches the set value, the controller starts the circulation pump automatically.The circulation pump makes heat-conducting liquid circulate automatically.Then liquid transfers heat to water by heat exchanger in the tank to heat the water
